IMPROVEMENT IN SIPHON-BOTTLE.

m Schedle refen'ed to in these het-tera Patent ana. making part of the l.

To' all whom it ma/y concer:

Be it known that LOHARLES J. GoNvERsn, of Boston, in the County of Suffolk, and State of Massaclusetts, have invented certain new and useful imp'oveinents in the detail of Construction and arrangenent of bottles designed to contain liquids under gaseous pressure and to discharge the same upon the opening of a valve in the manne' of a fountain.-

These pecularities are shown in the drawing, which represents, in vertical central section, a' bottle enbodying my improvements.

In this class of fountain-bottles, a tube, open at both ends, is enployed, which extends from the neck of the bottle where the tube is coufined, by having the tlange on its upper end pinched between suitable dcvicesinserted in the neck of the bottle, the lower end of the tube extending uearly to the bottom of the bottle, so that the compressed gas, which occupies' the upper part of the bottle, will,'wheu permitted to expand, force nearly all of the liquid out from the bottle .through the tube.

Now, my invention relates to specific means, and to their arangement and combination, for confining this tube and for closing the neck of the bottle, and it also relates tothe valvular arrangement and the means for Operating it, and for clirecting the escaping liquidcurrent.

The end of the bottle-neck is made as a concave ring, as seen at a, the lower part of which has a less internal diameter, or opening, than the upper part, so that the flange b of the metallic cup c may pass through the mouthcf the bottlv-neck and rest on'the contraction below.

The bottom of the cup c is pierced with an aperture large enough to admit the body of tube d,-which is prefe'ably of glass, said tube having a soft packingrim, e, located between its flange, f, and the met-al of the cup.

N ut-threads' are made in the upper part of the cup, into which the end of piece g .is screwed, down upon a Washer, h, 'of soft material placed over the flangeof the glass tube, soas to hold the tube firmly to the cup c, which cup is fi'mly held in place by the rubber Washer or ring l, which is made of such shape as to fit in the space `in the neck of the bottle above the cup, into which space it is crowded before the piece g is screwed into the cup c, and against the Washer h.

The top of' the 'piece has a cap, i, screwed into it, said cap having its outlet controlled by a valve, j, preferahly made of rubber, of the form shown, which valve is kept against its seat by the spring k, securely from accidental displacement and from falling, said spring being seatcd, as shown on the piece g.

The natter so far described completes the closing of the bottle, so that there can be no leakage and no escape of its contents until the valve is forcibly pressed away from its seat; and it will be seen that the press ure within the bottle will keep the valve constantly forced toward its seat.

The waslers 'or packing-rings e and h, and the rubber packing-ring l, efl'ectually prevent all leakage about the bottle-Beck and the parts inserted therein under all the contingencies of transportation and handling.

To depress the Valve j, to cause a flow from the bottle of its contents, and to give such a direction to the escaping current that it may be caught in a vessel held or placed at the side of the bottle, I make use of the curved tube m, the lower end of which fi'ts in the orifice of the cap i, so that it can .be moved freelyup and down therein, said end of the tube being notched where it comes into contact With the valve to allow free passage from the bottle.

1. I claim, in coinbination with a bottle, having its neck formed substantially as shown, the elastic ring l of corresponding formation, the flanged nut-threaded cup c, the screw-threaded piece g, and the tube at.

2. Also, in conbination with a valve-chanber, made in two parts, g and i, a valve supported by a spring resting-on one part and forcing the valve against its seat, made in the other part, substantially as described.

3. Also, the tube m, curved at one end and notched at the other, so as to act upon the valve and direct the escaping current, substantially as described;
